Definitions

  • the invention relates to a method for receiving paper reels in papermaking industry.
  • Recent apparatuses operate either pneumatically, hydraulically or by means of electric motors. The amount of energy they consume is considerable. It is generally known that the receiving can also be performed by a steel stopper, whereby the receiving is extremely vigorous and the cylindrical body will catapult back.
  • a usual procedure for receiving a cylindrical body is receiving which occurs by pneumatic or hydraulic cylinders. Then, energy is supplied to an extremely large cylinder and the receiving takes place by removing this energy from the cylinder, whereby it moves downwards. In practice, such arrangements provide satisfactory receiving but they consume a remarkable amount of energy.
  • Another conventional procedure is a steel stopper against which a cylindrical body comes. This procedure does not consume energy, because the cylindrical body climbs uphill, whereby its speed will decelerate. A disadvantage of this arrangement is that energy does not disappear but the cylindrical body will start to return downwards. Thus, this conventional arrangement is poor of its receiving properties and the receiving takes a long time.
  • a method according to the preamble of claim 1 is known from EP 1 216 945 A2 .
  • the object of the invention is to introduce a method which eliminates disadvantages of prior art and especially decrease consumption of energy and provide a better receiving capability.
  • a particular object is to introduce a method, by means of which, cylindrical bodies can be received controllably without consuming large amounts of energy and such that the system is not connected to any source of energy.
  • the object is namely to provide a method, by means of which, it is possible to reach considerable savings in costs and improvements in functionality for recent methods and apparatuses.
  • the object of the invention is provided by a method according to claim 1.
  • the receiving of cylindrical bodies utilises tight, self-restoring pressure elements, in which, the inflow and/or outflow of compressed air is adjusted and the motion speed of a cylindrical body is decelerated.
  • the apparatus for carrying out the method according to the invention restores to receiving readiness due to self-restoring material. Thus, there is no need to connect the apparatus to any source of energy.
  • the power of the receiving of a cylindrical body is adjusted by changing the size and/or number of outlet flues of the pressure elements.
  • the amount of return flow is adjusted by the size of the flue or flues of the pressure elements, chokers and/or check valves installed in them.
  • the power of return flow is advantageously adjusted by electromagnetic valves.
  • the receiving of a cylindrical body utilises several smaller pressure elements which are installed side by side and/or one after the other and such that no empty gaps remain in the receiving.
  • a tight, elastic pressure element which can be a hose, bellows, a rubber mat or some other tight and elastic element, includes within it self-restoring porous material which restores itself to the receiving form by itself.
  • the actual receiving and deceleration of the cylindrical body occurs by controlling the amount of air being let out.
  • the body starts to compress the pressure element to collapse, whereby pressure within the pressure element increases and starts to decelerate the advance of the cylindrical body.
  • the pressure increases and its outlet are controlled such that a part of air as large as possible has discharged at the end of receiving.
  • no thrust is applied from the stopper due to the pressure.
  • the self-restoring material restores itself so slowly that it applies no thrust to the cylindrical body. This method provides a good damping ability without the apparatus consuming energy.
  • the amount of air being let out depends on the weight and motion speed of the body being received.
  • the amount of choked outlet air is the energy which can be damped.
  • the restoring of the self-restoring material occurs in the invention so slowly that it incurs no thrust to the cylindrical body.
  • the method according to the invention is particularly used for receiving a cylindrical body, whereby energy is saved and other considerable advantages are provided.
  • Fig. 1 shows a typical receiving apparatus which utilises a pneumatic cylinder 2 and an arm 4 fastened to it when receiving.
  • the pneumatic cylinder 2 starts its motion from the effect of a sensor 3.
  • the receiver arm 4 and the cylindrical body 1 have almost the same motion speed.
  • the pneumatic cylinder 2 returns the apparatus and the cylindrical body has been received to a substation 5.
  • Such an apparatus is known and its use requires a lot of energy.
  • a cylindrical body 1 arrives downwards and goes over a substation 5 and hits a steel stopper 6 which includes a pneumatically-operated cylinder 2 as pressurised.
  • the pneumatically-operated cylinder does not assist in receiving but operates as a pneumatic spring.
  • Such an apparatus is known and, irrespective of using the pneumatic cylinder 2 or not, a reel starts to roll at an extremely high kinetic energy back in the incoming direction.
  • Fig. 3 shows an arrangement for carrying out the method according to the invention.
  • a cylindrical body 1 (a reel) arrives downwards and goes over a substation 5 and hits an apparatus for carrying out the method according to the invention in which a pressure element 7 decelerates the motion speed of the reel when compressing. Air discharges controlledly from discharge flues 8 of the pressure element, and the apparatus does not incur thrust as the cylindrical body departs back to the substation 5 from a considerably less sloping stopper 9.
  • This apparatus improves the stopping of the cylindrical body substantially compared with the known apparatus/method shown in Fig. 2 and saves energy significantly compared with the known apparatus/method shown in Fig. 1 .
  • Figs. 4 , 5 and 6 show by usual graphic symbols and conceptual drawings of the field the operation of an apparatus for carrying out the method according to the invention.
  • the apparatus includes a pressure element 7 manufactured of elastic material within which is located porous material 10.
  • the pressure element includes air discharge flues 8 the size of which can be adjusted by electromagnetic valves 13 or by check valves 15.
  • the elastic pressure element 7 and the porous self-restoring material 10 make the pressure element swell for receiving. Swelling speed can be adjusted by adjusting the amount of air flowing within by a choke 11. As the cylindrical body 1 hits the pressure element 7 in a way shown in Fig. 5 , the pressure within the pressure element 7 increases. The pressure increase provides the deceleration of the reel. The pressure increase can be adjusted by the number of the discharge flues 8 in the pressure element and by means of the size of the flue. Using electromagnetic valves 13 enables adjusting discharge flow as the weight and the speed of the cylindrical body varies by opening or closing the flues. When the pressure element 7 has compressed totally 14 in a way shown by Fig. 6 , choked outflown air has increased pressure in the pressure element and performed damping.
  • the apparatus restores to receiving readiness by the force of the self-restoring material. This speed is adjusted by adjusting the amount of inflowing air by chokers 11.
  • the choker 11 also provides that the self-restoring material 10 does not push the cylindrical body 1 and thus accelerate its speed.
  • Figs. 7 and 8 show two different implementations of the apparatus for carrying out the method according to the invention.
  • Fig. 7 there is one pressure element 7 which is filled with self-restoring material 10. This receives a very wide cylindrical body 16, but the power of receiving weakens at the point of a narrow cylindrical body 1. This is due to the fact that there is room in the pressure element where the air escapes and from which it can deliver energy back to the reel.
  • Fig. 8 shows several smaller pressure elements 7 which are filled with self-restoring material 10 in an apparatus for carrying out the method according to the invention.
  • the pressure elements are installed side by side and in two rows.
  • Such an apparatus will receive both the wide 16 and the narrow 1 cylindrical body well. This is due to the fact that air discharges totally from the pressure elements in the receiving situation and no remaining energy occurs.
  • By setting the pressure elements in this way no empty gaps remain in the receiving and the receiving of the cylindrical body is improved.
  • Fig. 9 shows a practical embodiment of a pressure element in an apparatus for carrying out the method according to the invention.
  • Elastic and tight surface material 17 of the pressure element is sealed at ends 18 and thus made air-tight.
  • self-restoring porous material 10 such as e.g. foam plastic.
  • the pressure element is provided with one tight connection or several tight connections using pneumatic connectors 20 and retaining nuts 19.
  • Fig. 10 shows an embodiment of the apparatus for carrying out the method according to the invention.
  • Self-restoring pressure elements 7 are installed one after the other on a slightly sloping plane 9. As a cylindrical body 1 arrives, it starts to compress the pressure elements 7 which provide increase in pressure and deceleration of the cylindrical body.
  • Fig. 11 shows another common embodiment of the apparatus for carrying out the method according to the invention.
  • a self-restoring pressure element 7 is installed in a wall 21. As a cylindrical body 1 hits the wall, the pressure element performs damping.
  • Fig. 12 shows an embodiment of the operation of the apparatus for carrying out the method according to the invention. The operation corresponds to that shown in Fig. 3 .
  • the apparatus is shown with a self-restoring pressure element 7 which includes porous material 10, a valve 13 and a choker 11 of inflowing air.
  • the method according to the invention is utilized in the papermaking industry where a lot of paper reel transfers are performed.
  • the construction according to the invention enables gentler reel handling without consuming energy.
